Impact of Frictional Heat Generation upon Temperature of Sesame Paste Flow through Screw-expeller

Rajaratnam Shanthini¹, S.A.V. Kumar ², S.M.D.T. Sandaruwan¹
¹University of Peradeniya, Peradeniya, Sri Lanka
²Texlan Center (Pvt) Ltd, Minuwangoda, Sri Lanka

Temperature of sesame paste flowing through a screw-expeller was studied. Screw-expeller used consisted of a rotating tapered screw and a constant-inner-diameter stationary barrel. Since screw diameter was much larger than the sesame paste thickness, an unwrapped model was employed with ... Read More

Collection efficiency of particles on a ribbon in a turbulent air flow

R. Divigalpitiya[1]
[1]3M Canada Company, London, Ontario, Canada

The collection efficiency of aerosol particles on a ribbon in a turbulent flow is analyzed using COMSOL Multiphysics. The flow field is solved using Chemical Engineering module and particle tracing plots are obtained using equations of motion including Khan and Richardson drag force. A ... Read More

Modeling Solid-Liquid Settling System as a Two-Phase Flow Problem

L. Gyurik [1], A. Egedy [1], Zs. Ulbert [1],
[1] University of Pannonia, Veszprém, Hungary

Sedimentation is a challenging two-phase problem to model and simulate. Many applications in the industry use sedimentation for separation. For example treatment of wastewater often carried out in settling basins. Different types of the sedimentation process include independent and zone ... Read More

[1] Klipsch Group, Inc., Indianapolis, IN, USA

COMSOL Multiphysics® simulation software is receiving a lot of attention in the loudspeaker industry thanks to the quality of the results it provides making it an essential tool to optimize geometries so that the best reproduction capabilities of the loudspeaker system are achieved. ... Read More

Modeling Internal Erosion Processes in Soil Pipes

J. L. Nieber [1], G. V. Wilson [2], G. A. Fox [3],
[1] University of Minnesota, St. Paul, MN, USA
[2] United States Department of Agriculture - Agricultural Research Service National Sedimentation Laboratory, Oxford, MS, USA
[3] North Carolina State University, Raleigh, NC, USA

The erosion of the interior of soil pipes is an important process in the fields of geomechanics and geomorphology. Soil pipes can form in water holding structures like dams and levees, and water flow through these structures becomes concentrated into the soil pipes as they evolve by the ... Read More

Surface Acoustic Wave Based MEMS Resonator

S. Dixit[1], R. C. Jain[1]
[1]Jaypee Institute of Information Technology, Noida, Uttar Pradesh, India

Surface Acoustic Waves (SAW) is the acoustic wave that propagates along the surface of the substrate with amplitude decaying exponentially away from the surface. A basic SAW device consists of two IDT’s on a piezoelectric substrate such as quartz. Surface Acoustic Wave can be ... Read More

Effects of Thermal and Electro-Osmotic Flux on Grounding Electrodes

I. Ferreira de Rezende Costa¹, M. C. Barbosa¹, A. De Oliveira Costa Neto²
¹UFRJ, Rio de Janeiro, RJ, Brazil
²UFVJM, Teófilo Otoni, MG, Brazil

Electricity has become the main source of heat, power, and light used in the modern world. Much of the technological advances made over the last few decades are due to electrical energy. One of the essential components of the electrical system is the grounding network. The continuous ... Read More

Acoustic Upside-Down Levitator with a Solid Sample

L. Holitzner [1], E. G. Lierke [2],
[1] Paul Scherrer Institut (PSI), Villigen PSI, Switzerland
[2] tec5 AG, Oberursel, Germany

Introduction: Acoustic levitators are used to levitate small samples (ca. 0.01 - 6 mm) at a stable position in a gas or liquid environment. Acoustic levitators were first developed und used for experiments in space (1970s, by NASA / ESA), the application later became terrestrial (1990s). ... Read More
